Measuring Input Wiring
IM 04P01B01-01E
Thermocouple input
b –/B +/A
Extension leadwire
DC voltage input, 1-5V input,
and ON/OFF input
b –/B +/A
–
DC voltage
1-5V
ON/OFF
Note
RTD input terminals A and B on the dot model are isolated on each channel. Terminal b is
shorted internally across all channels. However, for 3 legs isolated RTDs (/N2 option), input b is
also isolated for each channel.
Resistance temperature detector input
Leadwire resistance:
10 Ω max./wire. The resistance
of the three wires should be
equal.
DC current input
Shunt resistor
Example: For a 4 to 20 mA
+
input, a shunt resistor of
250 Ω ± 0.1% can be used to
convert to 1-5V input.
